The welfare cost of bank capital requirements

Capital requirements are the cornerstone of modern bank regulation, yet little is known about their welfare cost. This paper measures this cost and finds that it is surprisingly large. I present a simple framework, which embeds the role of liquidity creating banks in an otherwise standard general equilibrium growth model. A capital requirement limits the moral hazard on the part of banks that arises due to deposit insurance. However, this capital requirement is also costly because it reduces the ability of banks to create liquidity. The key insight is that equilibrium asset returns reveal the strength of households’ preferences for liquidity and this allows for the derivation of a simple formula for the welfare cost of capital requirements that is a function of observable variables only. Using US data, the welfare cost of current capital adequacy regulation is found to be equivalent to a permanent loss in consumption of between 0.1% and 1%.     

Sovereign credit ratings and bank funding cost: Evidence from Africa

This paper aims to examine the relationship between sovereign credit ratings and funding costs of banks and also the relationship between sovereign credit ratings. Using over 300 banks operating in Africa from 2006 to 2012, the study investigates sovereign ratings’ impact on funding cost. The long term domestic sovereign ratings announced by Fitch and Standard & Poor’s during the period under study were used. The panel made use of Generalized Method of Moments estimation strategy for funding cost. The findings of the study indicate that sovereign ratings upgrades have an inverse and statistically significant relationship with funding costs. The findings suggest that sovereign rating upgrades makes it easier for banks to access funds from the capital and global market at a cheaper cost compared to rating downgrades. The study recommends and encourages emerging economies to use the services provided by credit rating agencies since these agencies may help improve accessibility of funds in the international markets by banks. It is recommended that sovereign rating should be considered as a supplement and not a substitute to our own perceived judgement and research.     

Do capital requirements affect cost efficiency? Evidence from China

This paper contributes to the debate on the effect of capital requirements on cost efficiency. We study the relation between capital ratio and cost efficiency for Chinese banks over the period 2004–2009, taking advantage of the profound regulatory changes in capital requirements that occurred during this period to measure the exogenous impact of an increase in the capital ratio on banks’ cost efficiency. We find that such an increase has a positive effect on cost efficiency, the size of which depends to an extent on the bank's ownership type. Our results therefore suggest that capital requirements can improve cost efficiency.     

Modelling Credit Risk for SMEs: Evidence from the U.S. Market

Considering the fundamental role played by small and medium sized enterprises (SMEs) in the economy of many countries and the considerable attention placed on SMEs in the new Basel Capital Accord, we develop a distress prediction model specifically for the SME sector and to analyse its effectiveness compared to a generic corporate model. The behaviour of financial measures for SMEs is analysed and the most significant variables in predicting the entities' credit worthiness are selected in order to construct a default prediction model. Using a logit regression technique on panel data of over 2,000 U.S. firms (with sales less than $65 million) over the period 1994–2002, we develop a one-year default prediction model. This model has an out-of-sample prediction power which is almost 30 per cent higher than a generic corporate model. An associated objective is to observe our model's ability to lower bank capital requirements considering the new Basel Capital Accord's rules for SMEs.     

The signaling role of trade credit: Evidence from a counterfactual analysis

We quantify the signaling effect of trade credit on bank credit in a sample of US firms. Our identification strategy relies on the signaling model by Biais and Gollier (1997) and accounts for the endogeneity due to the possibility of self-selection and the simultaneity between banks’ and firms’ credit decisions. We find that: (i) firms’ self-select into trade credit; (ii) firms’ decision to use trade credit results in a higher chance of obtaining bank credit and a lower cost than the counterfactual ones they would have faced if not using trade credit.     

The cost of capital and optimal financing policy in a dynamic setting

This paper revisits the Modigliani–Miller propositions on the optimal financing policy and cost of capital in a dynamic setting. In an environment without taxes and bankruptcy costs, the results are generally consistent with the Modigliani–Miller Propositions 1 and 2. However, the first proposition should be presented and interpreted more carefully, as given firm characteristics, there is only one optimal capital structure. Thus, a firm’s capital structure is relevant. A relaxation of assumptions about either taxes or bankruptcy costs leads to conclusions that are generally different from those in Modigliani and Miller (1958). The model predicts that leverage and sales-to-capital ratios decrease but firm size and capital stock increase with the subjective discount factor of the firm’s manager if there are taxes and bankruptcy costs. The empirical analysis supports these predictions.     

The effect of increased disclosure on cost of capital: Evidence from China

This study examined the relationship between disclosure and the cost of capital. Prior studies empirically testing this relationship provided mixed findings, and also raised several concerns, such as the endogeneity of disclosure, the information disclosure environment, and the sample size. This study investigated this relationship based on data from the Chinese capital market where a unique institutional arrangement makes the disclosure exogenous. This unique characteristic, in conjunction with a less stringent information environment and a big sample size, helped address these concerns. Our findings confirmed the negative relationship between disclosure and cost of capital.     

Do credit unions use their tax advantage to benefit members? Evidence from a cost function

This paper examines whether the credit union income tax subsidy is passed along to members or consumed by managers. To that end, we estimate a translog cost function for credit unions and mutual thrifts that is tailored to the unique objectives of mutually owned depository institutions. We find that credit unions with residential common bonds have higher costs than mutual thrifts, but single common bond occupational and associational credit unions are more cost efficient. Thus, it appears that residential credit unions engage in expense preference behavior and hence redirect some portion of their tax benefit away from members.     

The role of credit ratings on capital structure and its speed of adjustment: an international study

Using an international dataset, we examine the role of issuers’ credit ratings in explaining corporate leverage and the speed with which firms adjust toward their optimal level of leverage. We find that, in countries with a more market-oriented financial system, the impact of credit ratings on firms’ capital structure is more significant and that firms with a poorer credit rating adjust more rapidly. Furthermore, our results show some striking differences in the speed of adjusting capital structure between firms rated as speculative and investment grade, with the former adjusting much more rapidly. As hypothesized, those differences are statistically significant only for firms based in a more market-oriented economy.     

The international transmission of bank capital requirements: Evidence from the UK

We use data on UK banks? minimum capital requirements to study the impact of changes to bank-specific capital requirements on cross-border bank loan supply from 1999Q1 to 2006Q4. By examining a sample in which each recipient country has multiple relationships with UK-resident banks, we are able to control for demand effects. We find a negative and statistically significant effect of changes to banks? capital requirements on cross-border lending: a 100 basis point increase in the requirement is associated with a reduction in the growth rate of cross-border credit of 5.5 percentage points. We also find that banks tend to favor their most important country relationships, so that the negative cross-border credit supply response in “core” countries is significantly less than in others. Banks tend to cut back cross-border credit to other banks (including foreign affiliates) more than to firms and households, consistent with shorter maturity, wholesale lending which is easier to roll off and may be associated with weaker borrowing relationships.     

The cyclical effects of the Basel II capital requirements

Capital requirements play a key role in the supervision and regulation of banks. The Basel Committee on Banking Supervision is in the process of changing the current framework by introducing risk sensitive capital charges. Some fear that this will unduly increase the volatility of regulatory capital. Furthermore, by limiting the banks’ ability to lend, capital requirements may exacerbate an economic downturn. The paper examines the problem of capital-induced lending cycles and their pro-cyclical effect on the macroeconomy in greater detail. It finds that the capital buffer that banks hold on top of the required minimum capital plays a crucial role in mitigating the impact of the volatility of capital requirements.     

Religious atmosphere and the cost of equity capital: Evidence from China

The cost of equity capital (ICC) is a crucial component of investment decisions and corporate performance evaluations. This study explores the effect of a region’s religious atmosphere on ICC and finds that ICC tends to be lower when stronger religious atmosphere is created. We further use the mediation effect method to clarify the specific channel through which religious atmosphere reduces ICC, and find that earnings quality, corporate investment efficiency and corporate social responsibility partially mediate the effect of religious atmosphere on ICC. Moreover, the relationship between religious atmosphere and ICC is more pronounced in firms with stronger external law environments and higher audit quality, indicating that formal institutions and religious tradition complement each other.     

The impact of imposing capital requirements on systemic risk

This paper examines the impact of imposing capital requirements on systemic risk. We use a static model on financial institutions’ risk-taking behavior to quantify the systemic risk in the cross-sectional dimension in both regulated and unregulated systems. Although imposing a capital requirement can lower individual risk, it simultaneously enhances systemic linkage within the system. By using a proper systemic risk measure combining both individual risk and systemic linkage, we show that systemic risk in a regulated system can be higher than that in an unregulated system. In addition, we analyze a sufficient condition under which the systemic risk in a regulated system is always lower.     

Finance and inequality: The distributional impacts of bank credit rationing

We analyze reductions in bank credit using a natural experiment where unprecedented flooding in Pakistan differentially affected banks that were more exposed to the floods. Using a unique data set that covers the universe of consumer loans in Pakistan and this exogenous shock to bank funding, we find two key results. First, following an increase in their funding costs, banks disproportionately reduce credit to borrowers with little education, little credit history, and seasonal occupations. Second, the credit reduction is not compensated by relatively more lending by less-affected banks. The empirical evidence suggests that a reduction in bank monitoring incentives caused the large relative decreases in lending to these borrowers.     

The impact of SEPA in credit transfer payments: Evidence from the euro area

This paper analyses the effect of the implementation process of the Single Euro Payments Area (SEPA) project on credit transfer payments in euro area countries during the period between 2008 and 2013. Using both univariate and multivariate fractional regression models, we found that, when controlling for socio-demographic, economic, technological and institutional factors, the progress in the migration to SEPA formats had a relevant positive impact on the share of payments made with credit transfers. Our results provide for the first time empirical evidence of the direct effect of the implementation of SEPA on payment habits and set the basis for the discussion of some of the possible implications of payments digitalization from both economical and societal perspectives.     

The impact of sovereign credit ratings on Eurobond yields: Evidence from Africa

The importance of sovereign credit ratings and Eurobonds issued by governments have come to the fore in Africa in the last decade. We examine whether changes in sovereign credit ratings impact Eurobond yields in 8 countries over the period of 2014–2019. Our approach reviews rating changes impact on Eurobond yields utilising the event study methodology. Our findings reflect that, on average, close to a third of rating actions directly impact bond yields in African countries. The statistically significant events include the downgrades of South Africa and Namibia to non-investment grade in 2017 reflecting critical transitions and bond investors’ reactions. Overall, the low percentage of a third, relative to previous international studies, suggests that largely rating changes are anticipated, do not have much new information and perhaps the perceived power of credit rating agencies may be overstated. In our view, the results reflect that pre-announcements of rating review dates since 2014 makes rating actions predictable and less impactful to bond yields. In addition, they reflect that bond investors adjust in real time as new information come in, resulting in less reliance on the opinions of CRAs and using their own assessments.     

The impact of changes in bank ownership structure on the allocation of capital: International evidence

A new wave of bank privatizations in the past decade has significantly changed the ownership structure of banking systems around the world. This paper explores how these changes affect the allocation of capital within countries. Increases in domestic blockholder ownership of banks adversely affect the allocation of capital through increased lending activity to less productive industries and to those with less dependence on external finance. This result is more pronounced in countries with higher levels of corruption. I find some evidence that foreign presence improves capital allocation efficiency by increasing lending to more productive industries, primarily in common law countries.     

The impact of FDICIA on bank returns and risk: Evidence from the capital markets

This study examines the impact of the Federal Deposit Insurance Corporation Improvement Act (FDICIA) of 1991 on bank stock returns and risk. We find that FDICIA had a generally positive effect on bank stock returns and resulted in a significant reduction in bank risk. The extent of the risk reduction varies based on the capitalization, size, and credit risk of the institutions with poorly capitalized, large, and high credit risk banks experiencing the greatest risk reduction. The results obtained using two separate control groups also bolster the conclusion that FDICIA’s passage resulted in a significant decline in bank risk.     

Politically connected boards,family and business group affiliations,and cost of capital: Evidence from Indonesia

We investigate the effect of politically connected boards (both supervisory boards [SBs] and boards of directors [BODs]) on cost of debt and equity capital of listed companies in Indonesia which has established a two-tier corporate governance system. The results, based on 250 firms, suggest that companies with politically connected SBs experience lower cost of debt and equity capital, whereas politically connected BODs have no association with cost of either debt or equity. Furthermore, we find that family firms and firms belonging to business groups with politically connected SBs enjoy lower cost of debt and equity capital. Our main results are robust to alternative measures and to tests for endogeneity.     

Full adoption of IFRSs in Brazil: Earnings quality and the cost of equity capital

The purpose of this paper is to investigate the impact of IFRS adoption on the earnings quality and the cost of equity capital of Brazilian companies. It is assumed that an increase in information contributes to a reduction in asymmetric information. A conjecture is that more efficient allocation of resources will result in a reduction in the cost of capital. The results show that the hypothesis of an increase in earnings quality after IFRS adoption holds true. The models used to analyze the equity cost of capital suggest a reduction in the cost of capital of around 7 basis points.
